Anyone use connectors like this? Are they as good as the videos for them make them look? Thanks in advance.

Waterproof shrink solder connectors?

This doesn't answer your question but anything that will waterproof a splice (soldered or crimped) would be a good idea.
Back in the day I had to replace a wiper motor on a Ford. The replacement from Ford used a different connector so cut and splice was required. in the supplied kit was small pieces of heat shrink tube that had a substance inside that created a waterproof seal after it was heated. I have never looked for it but I know it exists.

I used to use them all the time in the USAF. They work well. They are actually made for putting jumper wires on the shield of a cable.

You have to get those hot enough to melt the solder and some wire jackets are not high temp. You need to be careful. I use Raychem environmential splices, you need a tool, but they are aviation grade and weather proof. Many different sizes.
I have used these yesterday. They seemed to do a really good job. Very easy to use. My only issue was after I ordered these it took 4 weeks for delivery. Inexpensive waterproof is much better than crimping. The low temperature soilder melted quickly. As in the add I pulled on the connection as a trial and it didn't pull apart.
I think I’ll order me some and try them out. I’m in the middle of modifying a 5.9 Magnum wiring harness to go in my Duster so I’ll definitely have plenty of use for them.

HF sells a little "marine" shrink tube kit with the waterproof goop inside (cheap alternative)
The hb freight doesn't have the soilder like these. Cost more but I believe is a better product.
Remember you need a high temp heat gum like a HT 1000 to melt them properly. Not cheap.
Dual wall shrink tubing. Its shiny.
The cheap stuff is single wall and is flattened.
I buy the grote stuff all the time.
And i use the uninsulated butt connectors.

Ford motor co. recommends un-insulated crimp barrels for all wire splices. They are listed under part nos. WT-56814 for 22-18 AWG, WT-56815 for 16-18 AWG, and WT-56816 for 12-10 AWG.
Raychem environmental splices also use un-insulated barrels. both of these use adhesive lined heat shrink to seal the splice.
Raychem splices are fairly expensive, but they are the only ones most jet aircraft manufacturers approve for splicing wire.
A more economical way, is to order the barrels and heat shrink from Mouser or Digi-Key. The top picture is a Raychem and the bottom is from Mouser. both of these do an incredible job of splicing wire and the splice will more than likely outlive you.

I have a PILE Of them. Haven't used any yet. I do plan to though and I will let you know.

They are not great as they eliminate the crimp connection.
And as people have said, you need hi temp wire really for that type of thing.
Teflon is best.
Aircraft stuff.
For under the hood, I use a naked barrel with plain rosin solder and some heat shrink with sealant inside it to finish it off.
Takes a little more effort but for old auto wire it works better.
(How much are you going to be doing anyway.)
Aircraft is tinned wire.
Plain old automotive copper tends to be oxidized and the solder in those crimps may not flux enough for a good bond too.

Ok so these are connectors I ended up buying on amazon.
Here’s how they look on the wire before being shrunk
And here’s after it’s shrunk with the low (750*) setting on a heat gun. As you can see, the solder melted very nicely.
This was a test piece of wire so I grabbed ahold of bothe ends and pulled as hard as I could and the splice never budged. I’ve tried soldering before and it was a major fail. These connectors make splicing wires SUPER easy!! A++ from me!!

I purchased the Amazon brand and the plastic tends to start melting before the solder. I tried a mini butane torch as well as a heat gun with the same result. I would recommend a better quality item in the future. The idea is good, though.
The shrink tube shrunk before the solder melted on these but I just kept sweeping back and forth and turning the wire and the solder melted nicely without the plastic melting at all.
I purchased the same connectors. Except it took 6 weeks to get mine. A little fact that was not made clear at the time of purchase. They take orders than drop ship from China. But they are a good product.
